How do I make my local JavaScript project consume a local library?

Question

I have a JavaScript project, specifically, a create-react-app project, using yarn. I'm using Yup in my project and I have an idea how to improve it. I cloned Yup to my local hard drive to be able to edit it and work on it, but how do I make my local project use the local copy of Yup instead of the one installed from the npm package into node_modules ?

For those that know Ruby/Rails/Bundler, I'm after the JavaScript equivalent of

gem "somegem", path: "../../../somegem"

Answer 1

You can use npm link to consume a local library
